Horizon dashboard local/enabled directory not present in horizon container

[Sean Murphy]

In the kolla-ansible horizon queens container (ubuntu, binary), the directory

/usr/lib/python2.7/site-packages/openstack_dashboard/local/enabled

does not exist. This has implications when enabling optional dashboards
(eg heat) which assume the directory exists - see config_heat_dashboard
in kolla_extend_start.

When optional dashboards are required, kolla_extend_start fails when
trying to copy necessary files for the optional dashboards into the
above directory and consequently the container start process fails and
the container terminates.

Our ugly hack was to add

mkdir -p /usr/lib/python2.7/site-packages/openstack_dashboard/local/enabled

to the top of the kolla_extend_start file which solved the problem.

Same issue here:

cp: cannot create regular file '/usr/lib/python2.7/site-packages/openstack_dashboard/local/enabled/_1610_project_orchestration_panel.py': No such file or directory

Sean Murphy : Where did you add the line "mkdir -p /usr/lib/python2.7/site-packages/openstack_dashboard/local/enabled"? In the container?

Thank you.

You can also (manually) modify contents of your /etc/kolla/horizon directory to insert this modified file into the container. (Of course this breaks the automation which is kolla's main point, but I'm assuming this bug will be fixed quickly and this workaround will only be necessary for a short time).

Thanks Sean!
